I do this all the time. Let the first router be the DHCP server. Do not plug into the WAN port on the 2nd router. I always go from the first router to port 1, but it doesnt matter. I also make it a point to use Links-- as they are easy to configure to do this. I also make it a point to assign static IP's to any device permanently connected to this network. I had a customer with 3 Mac computers and 2 MAC laptops in the same home who wanted to add 7 different locations of the ROKU media servers. House was solid concrete and 3 stories high. He did however have CAT5 to each location where he wanted a server. It took me 2 days to get it up and working, then his MAC guy (so called expert) comes in and screws everything up. It worked great after I assigned static IP's to every device and he could even share his IPOD when he plugged it into the MAC.
